Traffic Control System for Emergency Vehicles using RFID and Sensors

Traffic lights are crucial for managing the flow of vehicles on the road. In particular, when there are emergencies, the traffic situation is getting worse. Emergency vehicles find it challenging to cross busy road during periods of traffic congestion. A medical facility must be reached by emergency vehicles like ambulances, or victims of accidents must be transferred to it as soon as possible. They could be late for rescue efforts because of traffic signals. Identification of emergency vehicles, control of traffic lights, and provision of a clear path for their travel are the objectives of traffic signal control for emergency vehicles. Emergency vehicles and traffic signals are connected by this system. The main element of this system that implements the control system is radio frequency Identification (RFID). The RFID tag helps to verify that emergency vehicles are leaving the traffic signal, and it also makes use of ultrasonic sensors to determine the density. The emergency vehicle can clear all junctions without wasting time at the traffic signals thanks to the theory that movement of the emergency vehicle near the traffic signal and changes in density reflect in changing the signal. This keeps happening until the ambulance arrives at its destination. These processes all took place without any assistance from humans.
